3550 RAM

Last Thursday there was a six hour power outage in my building. On Friday morning I discovered that a 3550 would not boot up. Port 1 goes orange and POST halts. I believe this indicates blown RAM. This is particularly disheartening because the switch was plugged into a UPS, which should have protected it from the electrical surge when power was restored. Apparently not!

I removed the cover and was surprised to find that nothing on this board is socketted. Has Cisco gone to a no replaceable parts design for this product? Or could the RAM possibly be on the bottom of the board? (Doesn't seem likely.)

Switches never have had socketed parts...

Hello Brad,

Thank you for your replies with the three links to Cisco information. They all point to the same conclusion I determined -- bad DRAM. Assuming that this is a correct diagnosis, the next logical question is "What can be done about it?"

When I clicked on the URLs in your sig, I received the following messages: Server not found Firefox can't find the server at

Is your web server down? Do you do component level repair? If so, how much do you charge to replace DRAM? From your experience, can you estimate the liklihood that there are no other problems with my switch?

Bob

I thought RAM was socketed in all Cisco devices to allow for upgrades to get more features and bug fixes from a newer, better, larger IOS. Now that I think about it, I agree that this is of greater value in a router than in a switch.

In my experience with PC troubleshooting, RAM seems to be highly succeptible to being ruined (presumably by unstable power), even more so than CPUs. So it would seem reasonable that board designers would allow for its replacement. Perhaps my experience is not typical of what others have found.

With switches, I typically find the quad-PHY chips driving each line out get fried, not RAM chips (depending on quite a bit the environment, in data centers, not so much, but where the wiring extends anywhere out to the building edges, much more so).

SmartNet on that box is probably around $250/year, and you'll get advanced hardware replacement (ie. cross-ship), and software updates. Seems alot cheaper than paying somebody to repair the switch, although there are some repair service people offering on eBay now-a-days for electronics component repair on gear such as this.

I think the 3550 has a lifetime hardware replacement warranty. If it does, Cisco will replace it free of charge. You send them the bad one, they will send you a refurb.

This is very interesting. Would this be true even if I don't have SmartNet? I'll look for warranty info on their site.

THANKS! Bob

Looks like its their standard 90 day warranty to me..

Hardware. Cisco Systems, Inc., or the Cisco Systems, Inc. subsidiary selling the Product ("Cisco") warrants that commencing from the date of shipment to Customer (and in case of resale by a Cisco reseller, commencing not more than ninety (90) days after original shipment by Cisco), and continuing for a period of the longer of (a) ninety (90) days or (b) the period set forth in the Warranty Card accompanying the Product (if any), the Hardware will be free from defects in material and workmanship under normal use.

I have't heard of Cisco ever having a lifetime hardware replacement warranty on any of their cisco branded hardware.
